DETAILED DESCRIPTION

Hereinafter, exemplary embodiments will be described in greater detail with reference to the accompanying drawings.

In the following description, same reference numerals are used for the same elements when they are depicted in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments. Thus, it is apparent that exemplary embodiments can be carried out without those specifically defined matters. Also, functions or elements known in the related art are not described in detail since they would obscure the exemplary embodiments with unnecessary detail.

FIG. 1 is a block diagram illustrating a configuration of a display apparatus according to an exemplary embodiment. The display apparatus 100 of FIG. 1 may be implemented by using various types of apparatuses such as a TV, a Personal Computer (PC), a laptop PC, a mobile phone, a tablet PC, a Personal Digital Assistant (PDA), an MP3 player, an electronic album, a kiosk, etc. Referring to FIG. 1, the display apparatus 100 includes a microphone 110, a controller 120, a display 130, and a graphic processor 140.

The microphone 110 is an element for receiving a voice signal of a user. The configuration of the microphone 110 may vary according to various exemplary embodiments. For example, the microphone 110 may include a microphone to directly receive the voice or may receive the user voice through a microphone provided on a remote controller. For a voice signal to be inputted, a microphone itself may be used, and a microphone which is included in an audio-visual (AV) apparatus, a computer, a portable computer, a mobile phone, a smart phone and a remote controller may be used.

The controller 120 is an element for controlling an overall operation of the display apparatus 100.

The graphic processor 140 is an element for configuring various screens. Specifically, the graphic processor 140 may generate a screen including various objects such as an icon, an image, and a text using an operator (not shown) and a renderer (not shown). The operator calculates attribute values of each object to be displayed, such as coordinates values, a shape, a size, and a color, according to a layout of the screen. The renderer generates screens of various layouts including objects based on the attribute values calculated by the operator. The screen generated by the renderer is provided to the display 130.

The display 130 displays various screens generated by the graphic processor 140. When the display apparatus 100 is a broadcast receiving apparatus for receiving and processing broadcast signals, the display 130 displays a broadcast program screen. When the display apparatus 100 downloads contents from various content providing servers such as an Internet Protocol (IP) server, the display 130 may display a content playback screen.

In addition, the controller 120 may control the graphic processor 140 to configure various screens such as a content selection screen through which various contents are selected, a main screen through which various menus are selected, a preference function screen which displays functions frequently used by the user, and a viewing history screen for guiding information on contents that the user has viewed. When a user's voice signal is input while a screen including at least one content is being displayed on the display 130, the controller 120 may control the graphic processor 140 to configure a resulting screen corresponding to the voice signal. The screen generated by the graphic processor 140 may be provided to the display 130 and displayed. In this case, the controller 120 may control the graphic processor 140 to configure a different resulting screen according to information of the content included in the screen.

Although the graphic processor 140 is an element separate from the controller 120 in FIG. 1, the graphic processor 140 may be implemented as a Graphic Processing Unit (GPU) provided in the controller 120. However, an extra illustration thereof is omitted.

FIGS. 2 to 11 are views illustrating an operation of a display apparatus according to various exemplary embodiments.

FIG. 2 is a view illustrating the performance of a different operation according to whether a content designated by a user's voice signal is included in a screen or not according to an exemplary embodiment.

As shown in FIG. 2, the display 100 may display a screen 210 including information of contents which are currently broadcasted. Such a screen 210 may be called various names such as a content selection screen or an ONTV panel. Referring to FIG. 2, thumbnail images 211-1 to 211-12 regarding viewable contents provided through a TV broadcast network, an IP network, and other various routes may be displayed on the screen 210 according to a predetermined layout.

When a user 10 utters a voice signal including a title of a content in the screen while the screen 210 is being displayed, the controller 120 displays a resulting screen 220 corresponding to the voice signal based on the voice signal and a status of the display apparatus 100. For example, when one of the plurality of thumbnail images 211-1 to 211-12 (for example, 211-9) is a thumbnail image regarding a content titled “AAA”, and the user 10 says “AAA, please.”, the controller 120 performs a control operation to directly select and replay the AAA content. Specifically, the display apparatus 100 may further include a processor (not shown) to replay the contents. The controller 120 may control the processor to replay the AAA content.

Accordingly, the display 130 displays the playback screen 220 of the AAA content. The AAA content may be provided from various sources. For example, when the display apparatus 100 has already stored the AAA content, the display apparatus 100 may directly replay the stored AAA content. When the AAA content is a broadcast program provided from a specific broadcasting station through a broadcast channel, the controller 120 controls a tuner (not shown) to tune to the corresponding broadcast channel and receives the broadcast program through the broadcast channel. When the AAA content is a content provided from a content providing server (not shown), the controller 120 controls a communicator (not shown) to access the content providing server using address information for acquiring the AAA content, and downloads the AAA content. The address information may be information that is pre-stored by the display apparatus 100. However, according to another exemplary embodiment, a server apparatus (not shown) interworking with the display apparatus 100 may provide the address information. The processor and the communicator mentioned in the above-described exemplary embodiment will be explained below in detail with reference to the drawings.

The user 10 may say a title of a content that is not included in the screen. FIG. 3 illustrates a case in which the user says “BBB, please” while the same screen 210 as in FIG. 2 is being displayed. When the BBB content designated by the user's voice signal does not exist in the current screen 210, the controller 120 displays a search result screen 310 which is a result of searching the BBB content. According to an exemplary embodiment, the search may be performed in various apparatuses. For example, the controller 120 of the display apparatus 100 may perform the search or an external server apparatus performs the search and provides a corresponding result to the controller 120. The search result screen 310 of FIG. 3 includes various items 311-1 to 311-12 including the keyword BBB.

When one of the items 311-1 to 311-12 is selected by the user, the controller 120 may replay a content corresponding to the selected item and output the content through the display 130.

According to the exemplary embodiments described above with reference to FIGS. 2 and 3, the display apparatus 100 may perform a different control operation according to whether information on the content designated by the user's voice signal is included in the current screen or not. Accordingly, the user may replay a specific content directly or may search for the content.

According to another exemplary embodiment, the display apparatus 100 may provide various resulting screens according to a kind of a screen currently displayed.

For example, when the user inputs the voice signal while the screen 210 including information on currently viewable contents is being displayed as shown in FIG. 2, the controller 120 may perform a different operation according to whether the content is included in the screen 210 or not.

On the other hand, when a screen 410 including information on contents preferred by the user is displayed as shown in FIG. 4, and the user inputs a voice signal designating a specific content included in the screen 410, the controller 120 may not directly replay the content and may perform a different control operation.

Specifically, as shown in FIG. 4, the display apparatus 100 may display the screen 410 including the contents that the user viewed before, relevant contents, similar contents, etc. Such a screen 410 may be called various names, such as a preference content screen, a MYCONTENTS screen, a viewing history content, etc. Referring to FIG. 4, thumbnail images 411-1 to 411-8 associated with the contents may be displayed on the screen 410 according to a predetermined layout. The layout of the screen 410 of FIG. 4 may be different from the layout of the screen 210 of FIGS. 2 and 3.

In this state, when the voice signal uttered by the user is input through the microphone 110, the controller 120 determines whether information on a content corresponding to the voice signal, namely a thumbnail image is included in the current screen 410 or not. When the thumbnail image (for example, 411-6) of the content corresponding to the voice signal exists, the controller 120 may display a search result screen 420 having various contents related to the corresponding content on the display 130. The search result screen 420 may include information on contents 421-1 and 421-2 that have been already viewed in relation to the corresponding content, and information on contents 421-3 to 421-5 that are newly viewable. When the corresponding content is a moving image consisting of a plurality of series, the controller 120 may distinguish between the series 421-1 and 421-2 that the user has already viewed and the series 421-3, 421-4, and 421-5 that the user has not viewed. When the user inputs a voice signal (for example, “part 3”) to designate a specific part of the content (for example, 421-3) while the screen 420 is being displayed, the controller 120 may directly replay the corresponding content and output the content.

FIG. 5 illustrates a case in which a content designated by a user's voice signal does not exist on the screen 410 which includes the information on the contents preferred by the user. For example, when the user inputs a voice signal “DDD, please” to designate a content (for example, DDD) that does not exist in the screen 410 as shown in FIG. 5, the controller 120 displays a search result screen 510 regarding the identification word DDD from among the keywords included in the corresponding voice signal. The search result screen 510 may include information on contents 511-1 to 511-n that have various titles including the text DDD.

FIG. 6 is a view to illustrate a case in which the user inputs a voice signal while a playback screen 610 of a specific content is being displayed. In this case, the controller 120 determines that a content (for example, DDD) included in the voice signal is not included in the current screen, and displays a search result screen regarding an identification word included in the voice signal. When the voice signal includes the same identification word DDD as in FIG. 5, the same search result screen 510 as in FIG. 5 may be displayed.

In the above-described exemplary embodiments, when an abbreviation for a title or another name is uttered in addition to the full name of the title, the controller 120 may display information on the contents corresponding to the abbreviation or another name.

As described above with reference to FIGS. 4 to 6, even when the user inputs the same voice signal, the display apparatus 100 may provide various resulting screens according to various conditions such as a type of a screen currently displayed, a content display status of the screen, etc.

In the above-described exemplary embodiments, the user inputs the voice signal to designate a specific content. However, the display apparatus 100 may receive a voice signal arbitrarily uttered by the user and may provide various resulting screens according to a meaning of the voice signal.

FIG. 7 is a view to illustrate an operation of the display apparatus according to such an exemplary embodiment. FIG. 7 illustrates a case in which the user 10 inputs a voice signal “What's that?” when a certain content screen 710 is being displayed. The controller 120 analyzes the user's voice signal and determines its meaning. Accordingly, the controller 120 determines the object indicated by the expression “that”, and displays a response message 720 corresponding to a result of the determining. FIG. 7 illustrates a case in which the user inputs the voice signal when an animation content having a penguin character named EEE is displayed. The controller 120 may configure the response message 720 “EEE is a penguin” in response to the user's question, and may display the response message 720.

The response message may be configured in various ways.

For example, the controller 120 may search a variety of information such as a title, character names, an additional explanation, etc., of the corresponding content from metadata of the currently displayed content. The controller 120 may control the graphic processor 140 to configure the response message 720 according to the result of the search.

According to another exemplary embodiment, the controller 120 may detect an image frame that is displayed at the time the user's voice signal is input. The controller 120 may detect an edge included in the detected image frame and may search related images corresponding to a shape of an object specified by the edge. When the related image is searched, the controller 120 may control the graphic processor 140 to configure the response message 720 to include the related image or to include a text with the related image.

In addition, the controller 120 may access a specific server apparatus based on address information linked with the corresponding content, and may control the graphic processor 140 to configure the response message 720 based on a text provided by the server apparatus.

FIG. 8 illustrates a state in which a web screen 810 is displayed. In this state, when the user inputs the voice signal “What's that?”, the controller 120 may display a response message 820 based on information from a web server (not shown) which provides the currently displayed web screen 810. In FIG. 8, the response message 820, displaying information indicating that the currently displayed site is the FFF portal site is illustrated.

For another example, the controller 120 may control the graphic processor 140 to configure the response message 820 to include a Uniform Resource Locator (URL) of the web screen 810 currently displayed. FIG. 9 is a view to illustrate an exemplary embodiment in which the user inputs a certain voice signal while a content selection screen, which includes information on at least one content, is being displayed. Referring to FIG. 9, a content selection screen 910 may include thumbnail images 911-1 to 911-12 relating to viewable contents.

The controller 120 may highlight one of the thumbnail images 911-1 to 911-12. In FIG. 9, the second thumbnail image 911-2 is highlighted. When the user manipulates a direction key provided on a remote control apparatus or inputs a voice signal indicating a direction, the controller 120 may move the highlighted area of the display in a direction corresponding to the direction key or voice signal. In this state, when the user inputs the voice signal “What's that?”, the controller 120 may control the graphic processor 140 and the display 130 to display a detailed information screen 920 linked with the currently highlighted thumbnail image 911-2. For example, when the corresponding thumbnail image 911-2 is a movie content, the detailed information screen 920 may include a variety of information such as a movie title, a language, a running time, a story, a main scene, etc.

In addition, when the user inputs a voice signal “Show me that!”, the controller 120 may control the processor to directly replay the content corresponding to the currently highlighted thumbnail image 911-2 and may display a replay screen thereof on the display 130.

According to the various exemplary embodiments described above, the display apparatus can provide various resulting screens according to an operation status of the display apparatus even when the user inputs the same voice signal.

In addition, even when the user inputs the same voice signal, the display apparatus may perform a different control operation according to an operation status of the display apparatus.

FIGS. 10 and 11 illustrate an operation of a display apparatus according to another exemplary embodiment. According to the present exemplary embodiment, the display apparatus may perform a different control operation according to an operation status of the display apparatus even when the user inputs the same voice signal.

In FIGS. 10 and 11, the user inputs a voice signal “Increase, please.” In FIG. 10, a screen 1010 having nothing to do with an audio volume is displayed. Specifically, the display apparatus 100 may display the screen 1010 including a plurality of objects 1011-1 to 1011-8. For example, the content selection screen including the thumbnail images regarding the viewable contents or the screen for the user preference contents may be displayed as shown in FIGS. 2 to 5.

In this state, when the voice signal “Increase, please” is input, the controller 120 may determine that the intention of the user 10 is to magnify the screen 1010. Accordingly, the controller 120 may control the graphic processor 140 to configure a screen 1020, to include the objects 1011-1 to 1011-8 of screen 1010 in a magnified form. When all of the objects 1011-1 to 1011-8 cannot be included in the one screen 1020 as a result of the magnifying, the number of objects included in the one screen 1020 may be reduced. In FIG. 10, eight objects 1011-1 to 1011-8 are included in the pre-magnification screen 1010, whereas only four objects 1011-1, 1011-2, 1011-5, and 1011-6 are included in the post-magnification screen 1020. When the voice signal “Increase, please” is repeatedly input several times, the controller 120 may control the graphic processor 140 to continue magnifying the objects 1011-1 to 1011-8. In addition, when the voice signal is input more than a predetermined number of times, the controller 120 may control the graphic processor 140 to configure one of the objects 1011-1 to 1011-8 (for example, 1011-1) to be a full screen size, so that the one of the objects 1011-1 to 1011-8 is displayed on the entire display. Although each object 1011-1 to 1011-8 is displayed in the form of a thumbnail image in FIG. 10, the objects may be implemented in various forms such as a text, a photo, an image, etc.

FIG. 11 illustrates a state in which a moving image content is replayed and a playback screen 1110 thereof is displayed. In this state, when the user 10 inputs the voice signal “Increase, please”, the controller 120 may determine that the user's intention is to turn up the audio volume. Accordingly, the controller 120 may increase the audio volume up to a predetermined level. In addition, the controller 120 may control the graphic processor 140 to configure a Graphic User Interface (GUI) 1120 indicating an audio volume status.

In FIGS. 10 and 11, the voice signal “Increase, please” is input by way of an example. However, when a voice signal “Decrease, please” is input, the controller 120 may perform a different operation such as reducing a size or turning down an audio volume according to a kind of a screen.

According to the various exemplary embodiments as described above, the display apparatus may perform various operations according to an operation status of the display apparatus, even when the user inputs the same voice signal.

In the above-described exemplary embodiment, the display apparatus 100 receives the voice signal and processes the voice signal. However, a broadcast receiving apparatus (for example, a set-top box) without a display may perform the above-described processing operation. When a user's voice signal is input while the display apparatus is displaying a screen including at least one content, the set-top box may configure a different resulting screen, corresponding to the voice signal and according to a content status, and may provide the resulting screen to the display apparatus. Consequently, the resulting screen corresponding to the voice signal is displayed on the display apparatus. The resulting screen configured by the broadcast receiving apparatus may be configured according to various exemplary embodiments as described above with reference to FIGS. 2 to 11. Illustration and explanation of the configuration and operation of the broadcast receiving apparatus will be omitted.

FIG. 12 is a flowchart illustrating a method for providing content information of a display apparatus according to an exemplary embodiment.

Referring to FIG. 12, when the display apparatus 100 displays a certain screen (S1210), the display apparatus 100 may receive a user's voice signal (S1220). The screen may be implemented in various ways as described above with reference to FIGS. 2 to 11. When the user's voice signal is input, the display apparatus 100 may configure a resulting screen corresponding to the voice signal to be displayed differently according to a content status in the screen, and may display the resulting screen (S1230). Such an operation may be independently performed by the display apparatus 100. However, this should not be considered as limiting. According to an exemplary embodiment, the above-described operation may be performed in a display system including a text converter, the display apparatus 100, and a server apparatus.

FIG. 13 is a block diagram illustrating a configuration of a display system according to an exemplary embodiment. Referring to FIG. 13, the display system 1300 includes a text converter 1310, a display apparatus 100, and a server apparatus 1400.

When a voice signal is input, the display apparatus 100 may transmit the voice signal to the external text converter 1310. The text converter 1310 is an apparatus that converts the voice signal transmitted through the display apparatus 100 into a text, and provides the text to the display apparatus 100. According to an exemplary embodiment, the text converter 1310 may be implemented by using a separate server apparatus or may be included in the server apparatus 1400.

The text converter 1310 may recognize the voice by using at least one of various recognition algorithms, such as a dynamic time warping method, a hidden Markov model, a neural network, etc., and may convert the recognized voice into the text.

panel_text: title1, title2, command1, command2, etc.

contents_title: title-1, title-2, title-3 . . . , title-n

alias-title: a-title-1, a-title-2, a-title-3, . . . , title-n

content_num: n

content_id: ID-1, ID-2, . . . ID-n

For another example, when a specific content is replayed, the display apparatus 100 may transmit the following status information:

device_status type: EPG

content_info: content-id-001

content_time: 20130102-10:00
